Paul, I have several of your boards including the excellent "kit" for the 516-F2 and also in all fairness,? I stand corrected!?

The L-4B "Harbach" board is indeed a "Harbach Board"!!? I have one in my L-4B, and another one is going into an HT45 and maybe an HT33 (both using the OEM L-4B power transformer)

They also do not have parallel diode resistors and caps and I am not going to add them.?? (it appears they're NOT really needed anymore using quality modern silicon diodes)
